* feat: render Reviews page diffs with pierre MultiFileDiff
The Reviews detail page used a hand-rolled hunk renderer with no syntax
highlighting. Switch it to the same pierre MultiFileDiff + theming the agent
chat git panel uses.
- review-diff API now returns full original/modified file contents instead of
hunks, via a shared build_pr_diff_files helper extracted from thread_api
- findings render as right-anchored markers (pierre line annotations); focus
highlight uses selectedLines; floating finding card still anchors to the marker
* feat: auto-collapse a review diff card when marked as viewed
* fix: URL-encode file path in Contents API fetch
Filenames containing reserved URL characters (#, ?) were truncated, so those
files rendered as empty/unrenderable. quote(path, safe='/') preserves the path
separators while escaping the rest.

* fix: Reviews tab — anchored finding card, paginated list, file tree truncation
- Finding card now tracks the diff anchor while scrolling instead of staying
frozen in the viewport; auto-hides when its diff card collapses (including
collapse via mark-as-viewed) and on click outside
- Checks section capped with max height + scroll
- /reviews paginated (page size 20) with has_more, filtered to the current
user's PRs by default with an All toggle; PR author login now stored in
reviewer thread metadata
- File tree truncation marker overlapped filenames because the sidebar bg
was transparent; use the opaque sidebar color
* fix: finding card tracks anchor 1:1 while scrolling
Drop the vertical viewport clamp — it pinned the card at the clamp
boundary while the highlighted lines kept scrolling, breaking the
attachment.
* fix: anchor finding card with Base UI popover
Replace manual fixed-position tracking (laggy: setState per scroll
frame) with a Popover anchored to the finding's diff row. Floating UI
tracks the anchor outside React renders, so the card moves 1:1 with
the content and scrolls out of view with it. Unanchored findings keep
the fixed top-right card.
* fix: lock finding card to diff scroll
Replace the Base UI popover (async repositioning, paints a frame behind
native scroll) with a card absolutely positioned inside the scroll
container, so it scrolls with the diff in the same compositor frame.
Scroll moves to the ReviewBody root, side panel becomes sticky.
Position recomputes only on layout shifts via ResizeObserver.
